Abstract: 7813. Roberts, T. April 4. Measured quantities, delivering.-In apparatus for filling bottles, jars, cans, collapsable tubes, and like receptacles with liquids or semi-liquids, the supply valve is electrically controlled so that it closes automatically when the desired quantity of liquid has been supplied to the receptacle. In the apparatus shown in Fig. 2, the vessel c to be filled is supported on the pan c<1> on the lever arm c<2> pivoted at c<3>. The supply valve in the casing a' is opened by the lever b', actuated through the rod b<3> and slide b<2> from the treadle b, and is held open during the filling- operation by the bent extension d<5>, Fig. 3, of the pivoted armature d<3> of the electromagnet d<2>, or by a pin on the armature, engaging the lever b<4>. When the predetermined quantity of liquid, which may be regulated by means of the adjustable weight c<6> on the lever arm c<2>, has been delivered into the vessel c, the lever arm c<2> tilts, and closes, between the post e and the contact e', the circuit of the electromagnet d', which thereupon releases the armature d<3> from the lever b<4>, thus allowing the supply valve to be closed by the spring b<6>. In the form shown in Fig. 6, as adapted for filling collapsable tubes, the tube f to be filled is supported in the socket f<1> on the lever arm f<2>, the socket being connected by the link f<6> to the pivot support g<9> of the lever arm f<2>, to maintain the tube in a vertical position. The supply valve a is held open by the electromagnet g<1>, to the armature g of which the valve spindle a<1> is connected, the circuit of the electromagnet being completed between the lever arm f<2> and the post g<14>. When the tube f is full, the lever arm f<2> is tilted into engagement with the insulation g<13>, so breaking the circuit, on which the valve a is closed by the spring a<6>. The apparatus may be arranged so that the valve is held closed by the magnet, and is opened by a spring when the circuit is broken. The electromagnet may also be replaced by a solenoid, and the valve may be of sliding, sluice, or other suitable form. When a long lift of the valve is required, the armature &c. may be raised by a hand or foot lever, the circuit being made and broken as above described. The apparatus may be arranged in multiple, for use in filling paint or like substances into cans &c. Fig. 8 shows another form of apparatus, in which the liquid is delivered from the nozzle n into the tipping vessel k, which, when full, tilts and delivers the liquid through the funnel c<9> into the bottle or other receptacle c, supported on an adjustable rest. The supply valve is controlled by the electromagnet g<1>, the circuit of which is made and broken between the vessel k and the insulated terminal k<5>. The quantity of liquid supplied at each operation is regulated by means of the adjustable weight k<3>. The mechanism may be protected by guards or covers, such as d<9>, Figs. 2 and 3, s', Fig. 6, and s, Fig. 8.
